Hi Mike,
can you tell me why you have that connector in the middle ?
It's not necessary, you could just have the hose-tail barb in the end of the pole hose.
It's a push-fit stop valve (one on each end of the pole hose) so when you pack away the pole hose can be disconnected both ends and the water stays in it. Less water on the floor and no lag when reconnecting. I put the small section (rectus to push-fit) in the lid of the backpack.
i cut the hose before the black handle with tap bit on
Yes, that's what I'm going to do with this one, just haven't got round to it yet! The tap's quite heavy/cumbersome and there are more connections to leak.
